When one being looks over the top of the urinal divider (with the urge of horniness) in order to see another being's penis. This can also be caused by the curiosity of the other man's size.
I was taking a piss and my boi Jeff stood at the urinal next to me. I didn't want to be a Portuguese Spy, but I've always wondered how big he was.
